.To all whom it may concern:

Be it known that I, EDWARD S. SAVAGE, a I citizen of the United States, and a resident of Brooklyn, in the county of Kings and State a of New York, have invented certain new and 1 useful Im rovements in Devices for Detach- Box- ,overs, of which the following is a i specification. g v This invention relates to devices for detaching box-covers, and has particularly for its ob]ect to provide means whereby the j tightly-fitting covers of tin boxes are easily removed. In the drawings, Figure 1 is a vertical section through the center of a round flat blacking-box of the style in which shoe blacking a or polish is usually sold and also through the center of the detaching device. In this figf'ure the box is shown closed. Fig. 2 is the same-section, but shows the cover raised by ff the detaching device; and. Fig. 3 is a side view of the box and detaching device. 1 1 represents a blacking-box of ordinary jjonstruction, 2 its cover, and 3 a bead upon the box to enga e and stop the cover. 4 is the detaling device, which is a lever ithatis pivoted'on the box by the bolt 5 below that part of the box that is engaged by the cover'when the latter is in position on the box. The bead 3 is not formed upon the box at the place 6 (see Fig. 2) where the detaching device is pivoted to the box, and so the detaching device lies flat against the box. Moreover,'the side of the box is bent slightly inwardly at this point, as shown in Figs. 2 and 3, so that the cover will fit down over the upper portion 7 of the detaching device. a

A shoulder 8 is formed upon the detaching device 4 at one side of the pivot 5, that lies beneath the cover when the latter is in place upon the box and is adapted todetach and raise it from the box. In the drawings such Specification of Letters Patent.

To open the box, the detachingdevice is turned in either direction. The lid is engaged in the crotch between the shoulder 8 and that part 7 of the device that is between the side of the box and the cover and is raised from the box is shown in Fig. 2.

What I claim is- 1. A device adapted to detach the cover from a box, consisting of a lever pivoted. to the side of the box, beneath the cover, having a part that is adapted to enter between the box and its cover, and an ofiset forming a shoulder at one side of its pivot and adjacent to said part that enters between the boxand cover, that is adapted to engage the lower edge of the cover, and thereby raise it.

2. A device adapted to detach the cover I from abox, consisting of a lever pivoted to the side of the box, beneath the cover, having a portion that is adapted to enter between the box and its cover, and offsets forming shoulders on each side of its pivot and adjacent to the part that enters between the box and cover, both shoulders being adapted .to engage the lower edge of the cover, and

thereby raise it.
